[#3985] Rename remaining data-explorer UI references to chart

[Brijesh-Thakkar]

Purpose

This PR completes the UI refactor from data-explorer to chart by updating all remaining
UI references that were not covered by the initial module rename.

The changes ensure consistent naming across the UI by:

• Renaming Angular selectors from sp-data-explorer-* to sp-chart-*
• Updating chart widget and config components (table, image, status, gauge, map, traffic-light,
  time-series, correlation, heatmap, indicator, and shared base widgets)
• Cleaning up remaining data-explorer references in UI comments and test (data-cy) attributes

This aligns the UI codebase with the already renamed chart module and avoids confusion caused
by outdated naming.

Remarks

• This PR contains UI-only refactoring and does not change runtime behavior or business logic.
• No backend, API, or data model changes are included.
• Changes were applied incrementally using small, focused commits to simplify review.
